IT industry is 'dishonest'

I was reading a article stating that the IT industry is dishonest because project estimation time is always under estimated.

The article is true project timescales are always under-estimated as the outsourcer wants the work. If they told the true timescale to the potential client and the fact that their requirements are too complicated they would not be awarded the work.

This leads to developers having to work 100 hour weeks to try and meet the deadline if the company is small, or if the company is large/off-shores they just throw more people on the project.
